Description

  According to the present invention, in a photographing surveillance system including a surveillance camera and a display device, surveillance video data input from one camera is edited, and an entire video of the surveillance area and a partially enlarged video of the focus area are displayed on one monitor screen. The present invention relates to a video aggregation display device that displays images simultaneously.

2. Description of the Related Art In recent years, photographing and monitoring systems equipped with a monitoring camera and a display device have been widely used for commercial purposes, financial institutions, and the like for crime prevention purposes.
In this imaging monitoring system, a request to view the entire video of the captured monitoring area and a request to view the video of an arbitrary part desired in the imaging area (hereinafter referred to as a target part) in detail coexist. .

  According to a conventional technique, an imaging monitoring system that displays two images of an entire monitoring area and an enlarged image of a target portion on a display device such as a monitor displays the entire image captured by a wide-angle camera on a first monitor. Look at the entire video displayed on the first monitor, and if there is a part you want to focus on, operate a pan-tilt camera whose camera field of view can be moved, acquire an enlarged video of the part of interest, and display it on the second monitor. An imaging monitoring system using “2 cameras + 2 monitors” has been used.

  However, in order to display two cameras, a wide-angle camera for acquiring a wide-range (entire monitoring area) video, a pan-tilt camera whose camera field of view can be moved, and a video captured by these two cameras, respectively. The configuration of “2 cameras + 2 monitors” composed of two monitors has problems such as equipment cost, installation work, maintenance, installation space, and the like, and a simple configuration has been demanded.

In recent years, with the advent of high-resolution CCD cameras and high-resolution monitors, it has become possible to acquire high-resolution wide-angle images with a single high-resolution and wide-angle camera using a digital interface. Needs have become apparent.
However, when the entire image of the monitoring area captured by the high-resolution CCD camera is displayed on a monitor of a normal size (for example, 14 inches), the entire monitoring area can be roughly checked, but the details of the image displayed on the monitor screen ( The detailed video of the part of interest was too small to be confirmed by human vision.
On the other hand, when an image of the entire monitoring area is displayed on a large-sized high-resolution monitor that can sufficiently confirm the details of the image captured by the high-resolution CCD camera with human vision, humans can be expanded by expanding the image display area (monitor screen). The observation range due to the monitor has increased, leading to an increase in the monitoring effort due to the monitor observation, and there were problems such as being unable to see the whole when viewed at close distances, and increasing the installation space of the monitor .

In other words, in a video surveillance system that requires real-time situation judgment and observes a monitor for a long period of time, human vision cannot fully correspond to the video displayed on the monitor screen, and high resolution CCD cameras and high resolution monitors are not compatible. I couldn't take full advantage of the performance.
Accordingly, in order to realize video monitoring with a single monitor, it has been required to provide video information in accordance with human vision.

  Therefore, the present invention displays the entire image of the monitoring region and the enlarged image of the target portion on one monitor screen at the same time so that it is possible to instantaneously determine where and what is happening in the monitoring region. It is an object of the present invention to provide a video aggregation display device that edits video data so that the position of the target portion on the entire video can be easily grasped.

  In order to achieve the above-described object, the video aggregation display device according to the present invention provides a monitor for displaying a video in a monitoring area on one monitor screen based on high-resolution monitoring video data input from one high-resolution camera. The monitor is divided so that one entire display area for displaying the entire video of the monitoring area and one or more enlarged display areas for displaying the partial enlarged video of the target portion are formed separately. A video aggregation display device that sets a screen display mode, edits video data in accordance with the display mode, and simultaneously displays the entire video of the monitoring area and the partial enlarged video of the target portion on one monitor screen. And means for associating the positional relationship of the portion of interest in the entire image displayed in the entire display area with the positional relationship of the partially enlarged image of the portion of interest displayed in the enlarged display area. It is.

In addition, according to the video aggregation display device of the present invention, the whole display area for displaying the whole video of the monitoring area is formed on the whole monitor screen, and at least one or two for displaying the partial enlarged video of the target portion. The monitor screen display mode is set so that the enlarged display area is superimposed on the entire display area, and the video data is edited in accordance with this display mode. An image aggregation display device for simultaneously displaying an enlarged image on one monitor screen, and an enlarged display area for displaying a positional relationship of a portion of interest in the entire image displayed in the entire display area and a partially enlarged image of the portion of interest Means for associating the positional relationship with each other.
Furthermore, the video integrated display device of the present invention can switch the display mode of the two monitor screens described above, and edits video data in accordance with the set display mode.

As described above, the video integration display device of the present invention is based on the monitoring video data input from one monitoring camera, and the entire video (low resolution) of the monitoring area and the enlarged video (high resolution) of the target portion. Is displayed simultaneously on one monitor screen, and an enlarged image of the target portion is displayed in accordance with the target portion and the positional relationship in the entire video so that the positional relationship of the target portion in the monitoring area can be easily grasped. It is.
This makes it possible to save and reduce the equipment cost, installation work, maintenance, and installation space by the configuration of “1 camera + 1 monitor”. It is possible to satisfy the demand to view in detail the video of a desired location (target portion) at an arbitrary position in the area.
In addition, each video is displayed so that its position can be easily grasped in the entire video displayed in the entire display area for the target portion displayed in the enlarged display area. In a video surveillance system that requires a long-term situation judgment and observes a monitor for a long time, it is possible to instantly judge where and what is happening, thereby reducing the monitoring effort.

  A preferred embodiment of the video integrated display device according to the present invention will be described with reference to FIGS.

  Thereafter, the video data synthesized (edited) by the video data synthesis block 8 is output as an NTSC signal via the D / A converter 13 and displayed on the monitor 14.

For example, as shown in “3-divided aggregated composite display” shown in FIG. 1A, the area around the arbitrary point (first attention point P ₁ ) in the entire video displayed in the entire display area is enlarged (shaded part). the image of the (partial enlarged image of the observed part), if the the whole display area for displaying the second enlargement display area formed separately from the monitor screen, at the location designated block 6 of the observed part, the first focus point P ₁ By acquiring position data and inputting this position data (point P ₁ ) to the enlarged area selector 7 (enlarged area 2), the enlarged area selector 7 (enlarged area 2) is centered on the position data (point P ₁ ). Is read out so as to be partially cut out from the monitoring video data stored in the enlarged frame memory 5 and partially enlarged of the target portion displayed in the second enlarged display area. The image data is input to the video data synthesis block 8, and the video data synthesis block 8 displays the enlarged video of the target portion in a second enlarged display area formed separately from the entire display area on the monitor screen. Video data is synthesized (edited).

Further, for example, as shown in “overlapping composite display” shown in FIG. 1B, an area around the arbitrary point (first attention point P ₁ ) in the entire image displayed in the entire display area is enlarged (shaded portion). and when displaying the image (partial enlarged image of the observed part) to the first larger image area was formed by superimposing on the entire display area is, at the position designated block 6 of the observed part, the first focus point P ₁ By acquiring position data and inputting this position data (point P ₁ ) to the enlarged area selector 7 (enlarged area 1), the enlarged area selector 7 (enlarged area 1) is centered on the position data (point P ₁ ). Is read out so as to be partially cut out from the monitoring video data stored in the enlarged frame memory 5 and partially enlarged of the target portion displayed in the first enlarged display area. Receives an input to the video data building block 8 as the image data, in the video data building block 8, enlarged image of the observed part in the first enlargement display area formed around said location data on a monitor screen (point P ₁₎ The video data is synthesized (edited) so as to be displayed.

  In the video integration display device of this embodiment, a high resolution video data photographed by the high resolution camera 1 using a 1280 × 1024 high resolution CCD camera (LVDS interface) 1 for video input and an NTSC monitor 14 for output. Is input via the differential receiver 2.

  LVDS (Low Voltage Differential Signaling) is a data transmission system that transmits data at high speed with a differential signal with a small voltage change, is resistant to external noise, and has a constant current on the transmission line. Operates stably even when conditions change. The differential receiver 2 is a device that receives data transmitted by the LVDS method.

  NTSC monitor 14 is used as the main standard for monitors used in Japanese surveillance systems, and the NTSC signal monitor screen is made up of 525 horizontal scan lines that are repeated 30 times per second (30 frames). Yes. In this embodiment, the synchronization signal generated by the display address counter 11 is converted by the D / A converter 13 and then output as the NTSC signal and input to the monitor 14.

  Further, a change-over switch 9 for selecting one of the display modes of “3-divided aggregated composite display” or “superimposed composite display”, and monitor screen construction and video data according to the display mode set by this change-over switch 9 The composition control block 10 for controlling editing is input to the display mode data selected by the selector switch 9 and the address data from the display address counter 11.

  That is, by selecting and setting one of the display modes of “3-divided aggregated composite display” or “superimposed composite display” with the changeover switch 9, a “3-divided aggregated composite display” or “superimposed composite display” monitor is displayed. Display mode data for constructing the screen (data relating to the size of each display area and the method of forming the display area) is input to the composition control block 10 and synthesized based on the display mode data and the address data from the display address counter 11. The control block 10 controls the reduction block 3, the enlargement area select 7, and the video data composition block 8, edits the video data according to the display mode, and displays it on the monitor screen.

  The reduction block 3 converts the resolution of the high-resolution video data acquired from the high-resolution CCD camera based on the display mode data (the size of the entire display area) of the display mode set by the changeover switch 9 (reduction / lowness). The entire reduced video data is stored in the entire frame memory 4. That is, the resolution of the monitoring video data is converted (reduced / reduced resolution) in accordance with the entire display area.

  In addition, the enlarged area select 7 receives the position data of the two portions of interest acquired in the position designation block 6 of the portion of interest, and the display mode data (set by the changeover switch 9 under the control of the composition control block 10). Based on the address data by the display address counter 11 and the size of the enlarged display area), the enlarged frame memory 5 storing the monitoring video data input from the high resolution CCD camera 1 stores the partial enlarged video data (high Resolution) is read out and input to the video data composition block 8.

  The video data synthesis block 8 receives the entire reduced video data (low resolution) stored in the entire frame memory 4 and the partial enlarged video data (high resolution) of the target portion read from the enlarged frame memory 5. Each video data is synthesized and edited based on the display mode data (display area forming method and the like) set by the selector switch 9 and the address data by the display address counter 11 under the control of the synthesis control block 10.

When high-resolution surveillance video data is input from the high-resolution wide-angle camera 1, the entire display area set in one section of the monitor screen (three-segment consolidated display) or the entire display area set in the entire monitor screen (overlapping) When displaying the entire video of the monitoring area in the combined composite display), the entire monitoring area cannot be displayed unless the monitoring video data is reduced. Therefore, the entire reduced video data obtained by reducing the monitoring video data in the reduction block 3 (reduced in resolution) in accordance with the size of the entire display area set by the display mode is stored in the entire frame memory, and this is stored in the video data. Input to the synthesis block 8.
And when displaying the partially enlarged video in the enlarged display area, if sufficiently high-resolution monitoring video data is input, it will be enlarged and displayed at the resolution ratio, so the partial enlarged video of the part of interest can be displayed without digital enlargement. Generate.

Next, a method for acquiring position data of a target portion displayed in an enlarged manner in the enlarged display area will be described with reference to FIG.
FIG. 3 is a block diagram showing the configuration of the position designation block 6 of the target portion.

  The video integration display device according to this embodiment (1) moves the cursor display on the monitor screen by a button operation by the operator, and displays the partial enlarged video at the location designated by the cursor on the whole video displayed in the whole display area in the enlarged display area. Means for displaying, (2) means for displaying a partially enlarged image of the sensor position in the enlarged display area when a sensor installed in the monitoring area is activated (sensor detects an abnormality), and (3 ) When a motion is detected based on the input monitoring video data, and a motion is detected, a means for displaying a partially enlarged video at the position where the motion is detected in an enlarged display area.

The target portion position designation block 6 shown in FIG. 3 acquires position data of two target portions. (1) Two pieces of position data of a location designated by the cursor on the entire video by the operator's button operation. the first such can store up to a second cursor position register (21R ₁ and 21R _2), (2) respective position of the sensor position of the first, second sensor installed in the monitoring area (28a and 28b) first storing data, a second sensor location register (22R ₁ and 22R _2), (3) first, second motion detection block provided so as to detect the motion from the monitor image data (29a and 29 b) first, provided with a second motion position register (23R ₁ and 23R _2), 2 two positions from the position data each location register stores for each store position data of the position of the motion input Select data, and a selector 25 for obtaining the position data of the target portion.

  In the first and second motion detection blocks (29a and 29b) provided so that two motions can be detected from the monitoring video data, the motion detection detected by the first motion detection block 29a is masked and the second motion is detected. The detection block 29b does not detect again.

Each register is provided with a corresponding flag. When a cursor input, sensor input, or motion detection is performed, the corresponding flag is activated (standing).
In this embodiment, _first and second cursor input flags (21F ₁ and 21F ₂ ) corresponding to the first and second cursor position registers (21R ₁ and 21R ₂ ), and first and second sensor position registers, respectively. _First and second sensor input flags (22F ₁ and 22F ₂ ) corresponding to (22R ₁ and 22R ₂ ) and _first and second motion position registers (23R ₁ and 23R ₂ ) respectively. 1 and a second motion detection flag (23F ₁ , 23F ₂ ) are provided.

Then, information on the state of each flag is input to the priority encoder 24, and the first and second highest priority among the activated (standing) flags are selected and the first selected And the second flag information are input to the selector 25, and the selector 25 converts the position data stored in the register corresponding to the selected flag into the position data of the target portion based on the two input flag information. As two.
In the priority encoder 24 of this embodiment, priorities are set in the order of motion detection, sensor input, and cursor input.

  That is, in the initial state (when there is neither motion detection nor sensor input), the position data of the cursor position register 21R that stores the location specified by the cursor on the entire video displayed in the entire display area is selected by the selector 25, and the target portion If the sensor is input (the sensor senses an abnormality), the position data in the sensor position register 22R that stores the sensor position has priority over the position data in the cursor position register 21R. When selected by the selector 25 and motion detection is detected by the block 29, the position data in the motion position register 23R is selected by the selector 25 in preference to the position data in the cursor position register 21R or the sensor position register 22R. And obtained as position data of the target portion.

  In this embodiment, each of the motion detection flag 23F and the sensor input flag 22F is configured to output a sensor via the OR logic circuit 30, and when any of the flags is activated (standing), Sensor output (alarm, interlocking with recording device, etc.) is output.

Further, the position data of the two portions of interest selected by the selector 25 are input to the rearrangement unit 26, rearranged by comparing the horizontal addresses, and the horizontal address is smaller in the enlarged area 1 in the enlarged area selector 7. The position data having the larger horizontal direction address is input to the enlargement area 2.
Note that the enlargement area 1 of the enlargement area selector 7 is the horizontal direction of the two enlargement display areas arranged in the left and right (horizontal direction) on the monitor screen in “three-division aggregated composite display” (see FIG. 1A). This is a means for acquiring from the enlarged frame memory 5 the partial enlarged video data of the portion of interest to be displayed in the first enlarged display area arranged on the smaller address (left side). This is means for acquiring from the enlarged frame memory 5 partial enlarged video data of a target portion to be displayed in the second enlarged display area arranged on the larger side (right side).

  Thus, when the display mode of the monitor screen is set to “3-divided aggregated composite display”, the first enlarged display area arranged on the left side has the enlarged frame memory 5 based on the position data with the smaller horizontal address. A partial enlarged image of the target portion extracted from (the target portion on the left side of the two) is displayed, and the second enlarged display area arranged on the right side is enlarged based on the position data having the larger lateral address. A partial enlarged image of the target portion (the right-side target portion of the two) extracted from the frame memory 5 is displayed, and the position (left and right) relationship of the target portion in the entire video and the focus displayed in each enlarged display area The positional relationship of the parts can be made to correspond.

  In addition, when the monitor screen is constructed so that the two enlarged display areas are arranged vertically (vertically) in the “3-divided aggregated composite display”, the enlargement area selector 7 has the one with the smaller vertical address (lower). Partial enlarged video data of the target portion to be displayed in the enlarged area 1 for reading out the partial enlarged video data of the target portion displayed in the enlarged display area from the enlarged frame memory 5 and the larger display area having the larger vertical address (upper side) And the enlarged area 2 for reading out the image from the enlarged frame memory 5, the position data input to the rearrangement unit 26 is rearranged by comparing the size of the vertical direction addresses, and the enlarged area 1 in the enlarged area selector 7 is arranged in the vertical direction. Enter the position data of the smaller address (lower side) and enter the position data of the larger vertical direction address (upper side) in the enlarged area 2 By Rukoto, the position (vertical) relationship observed part of the entire the video, the position of the observed part displayed on the enlarged display area (upper and lower) to correspond relationships.

  That is, the display mode of the monitor screen is set to “3-divided aggregated composite display”, the monitor screen is divided, and one entire display area for displaying the entire video (low resolution) of the monitoring area, and the portion of the target portion Two enlarged display areas for displaying an enlarged image (high resolution) are separately formed, and the video data is edited in accordance with this display mode, so that the entire image of the monitoring area and the partially enlarged image of the target portion are 1 When displaying simultaneously on the monitor screen of the monitor, a crosshair cursor for marking the position of the target portion on the entire image is displayed based on the position data of the target portion input from the enlarged area selector 7 to the cursor overlay 12. The position of the target part in the entire video can be confirmed, and the position (left and right) relationship of the target part displayed in each display area and the markings marked on the whole video are displayed. Since the position of the portion (left and right) relationship coincide, it is possible to easily grasp the position of the observed part.

On the other hand, to set the monitor screen display mode to “overlapping composite display”, to form an entire display area for displaying the entire image of the monitoring area on the entire monitor screen, and to display a partial enlarged image of the target portion The display mode of the monitor screen is set so that one or two enlarged display areas are superimposed on the entire display area, and video data is edited in accordance with this display mode, When the partial enlarged video of the target portion is simultaneously displayed on one monitor screen, an enlarged display area is formed around the position of the target portion in the entire video based on the position data of the target portion from the enlarged area selector 7 Therefore, it is possible to easily grasp where the target portion (enlarged partial image) displayed in each enlarged display area is in the monitoring area.
When the two enlarged display areas overlap, the enlarged display areas formed on the basis of the position data of the target portion with the higher priority in the priority encoder 24 are superimposed so as to be in front (up). To do.

  That is, in the monitoring system using the video aggregation display device according to this embodiment, an enlarged video of an arbitrary part in the whole video can be displayed together with the whole video by a button operation by the operator, and is installed in the monitoring area. When the sensor is activated (detects an abnormality), an enlarged image of the sensor position is preferentially displayed along with the entire image, and when motion is detected from the monitoring video data, the motion detection position is tracked and the motion is detected. An enlarged image of the detection position is displayed together with the entire image. Further, an enlarged video of the enlarged display area focused portion is displayed in correspondence with the positional relationship of the focused portion displayed in the entire display area.

By cursor display that moves the monitor screen by button operation by the operator, the cursor is specified at an arbitrary position in the entire image displayed in the entire display area, and the partially enlarged image at the specified position is displayed in the enlarged display area. In this case, the button state by the operator's button operation is read by the CPU 27, and the CPU 27 detects the position data of the place designated by the cursor in the entire video, and stores this position data in the cursor position register 21R.
When the cursor is designated at an arbitrary place in the entire video by operating the button, the cursor position flag is activated, and this information is input to the priority encoder 24, and the other flags are not activated (sensor input is also performed). When there is no motion detection), the position data of the cursor position register 21R is acquired as the position data of the target portion. In the initial state, when the enlarged image of the location designated by the cursor is always acquired, the cursor position flag is always set to the activated state.
As a result, in the initial state, the operator designates the cursor by operating the button on the entire image, and an enlarged image of the marked location is displayed in the enlarged display area.

When a sensor installed in the monitoring area is activated (detects an abnormality) and a sensor signal is input, the sensor input flag 22F is activated and information is input to the priority encoder 24.
As a result, the selector 25 obtains the position data of the sensor position register 22R that stores the sensor position corresponding to the sensor position in the entire video as the position data of the target portion in preference to the position data of the cursor position register 21R. To do.
As a result, the cursor display moves to the sensor position on the entire image, the sensor position is marked, and an enlarged image of the portion (sensor position) marked by the cursor display is displayed in the enlarged display area.

In other words, in the “3-divided aggregated composite display”, the cursor designated position or sensor position in the whole video displayed in the whole display area is marked by the cursor display, and the cursor designated position or sensor position is displayed in the enlarged display area. The partial enlarged video acquired as the center is enlarged and displayed, and the position (left / right) of the cursor specified position or sensor position in the entire video and the arrangement (left / right) of the enlarged video displayed in the enlarged display area arranged on the left and right And it comes to correspond.
In the “overlapping composite display”, an enlarged display area is formed around the cursor designated position or sensor position in the whole image displayed in the whole display area, and the cursor designated position or sensor position is displayed in this enlarged display area. The partial enlarged image acquired as the center is enlarged and displayed.

Furthermore, when a motion is detected from the monitoring video data and a change is detected in the video data (a motion is detected), the motion detection block 29 obtains a motion (change) detection position, and this motion detection position. Is input to the motion position register 23R, and the motion detection flag 23F is activated (standing).
Then, the position data of the movement position is input from the movement position register 23R to the selector 25, and information that the movement detection flag 23F is activated is input to the priority encoder 24. In the selector 25, the movement position register 23R The position data is preferentially acquired as the position data of the target portion.

As a result, the cursor display moves to the motion detection position (position of the moving body) on the entire video to mark the motion detection position, and an enlarged video of the portion marked by the cursor display is displayed in the enlarged display area.
If there is a moving object in the monitoring video data, motion detection occurs continuously and the detection position also moves. Thereby, the cursor display and the enlarged image in the entire image move, and the tracking image of the moving object can be acquired.
That is, acquisition of a tracking image of a moving object can be automated by a sensor function based on motion detection and its continuous operation.

In the “3-divided aggregated composite display”, the position of the moving object in the entire image displayed in the entire display area is marked by the cursor display, and the partially enlarged image acquired around the moving object in the enlarged display area Is magnified. Therefore, the enlarged display is always performed so that the center of the moving object is placed at the center of the enlarged display area, and the cursor display appears to move together with the moving object in the entire video.
Also, for example, when the positions of two moving objects in the entire image intersect and the left-right positional relationship is reversed, the images displayed in the enlarged display area are switched, and the position (left-right) relationship of the moving object in the entire image is switched. And the arrangement (left and right) relationship of the enlarged image of the moving body displayed in the enlarged display areas arranged on the left and right always correspond to each other.

  In the “overlapping composite display”, an enlarged display area is formed around the position of the moving object in the entire image displayed in the entire display area, and a partially enlarged image acquired around the moving object in the enlarged display area. Is enlarged so that the enlarged display area appears to move together with the moving object.
